International Journal of Security and Networks (IJSN), Vol. 9, No. 3, 2014

Abstract: As the needs of the convergence service are increasing, the IP multimedia subsystem (IMS) becomes an essential service platform to realise various types of new emerging services. The application areas for the services through the IMS are now diversified and the voice over IP (VoIP) is one of the widespread services. In this paper, an optimisation method is proposed for the special purpose VoIP call procedure when it is implemented based on the standardised IMS protocol. The signalling optimisation is discussed for the efficient realisation of the VoIP through the detailed investigation of the overall call procedures. Simulation results are also presented to show the quantitative effect on the system resource management that can be also utilised for the decision making for the future investment in the network systems.
